So I've had my GS4 since the beginning of June. I love everything about it, but for whatever reason it started to change the display time on its own to 2 seconds of inactivity. I switch it back to 30 seconds and all seems to be good for a few hours when it goes back to changing on its own. I did a factory reset and it seemed to fix it but it started changing again to the 2 seconds. If anybody has any suggestions as to what it is or what can be done for it I would greatly appreciate it! Thanks guys in advance. Oh and I am rooted.
